Compare And Contrast A Ct Scan And A Pet Scan

A pet scan which stands for positron emission tomography takes a very in depth look at your body past the point of its counterparts. Unlike a ct scan a pet scan shows problems at the cellular level.

Pet scans provide metabolic information and are increasingly read alongside ct or mri magnetic reso nance imaging scans which provide anatomic information.

Compare and contrast a ct scan and a pet scan. A pet scan uses nuclear medicine imaging to produce a three dimensional picture of functional processes in the body. But just as mri can not tell you if a spot is malignant or benign a pet scan just tells you which areas are active. Comparing ct and pet ct.

Pet scans are often used along with ct scans x rays or mri scans to obtain not only an image but also a clear idea of how tissue and organs are functioning in real time. Ct scans and mris are both used to capture images within your body. What is the difference between mri and pet scans.

The reality is that you cannot rely on a ct scan or ultrasound mri or blood test to tell you if you have cancer. The ct in ct scan stands for computed tomography. A pet scan on the other hand is a procedure with a certain level of radiation involved.

Pet scans allow physicians to look at the tissue and organs in your body on a cellular. Ct scan computer tomography and pet scan positron emission tomography are different but related imaging techniques. Lets compare them by potential hazard costs of the procedure and the time it takes to perform the procedure.

Most pet scans are done in a ctpet combination machine. A pet scan uses small amounts of radioactive substances called contrast materials for contrast within the body. So with a pet scan you are injected with the radioactive glucose you rest for 15 60 minutes to let it find the metabolically active cells and then you are put in the special petct scanner to collect the images.

A pet scan uses nuclear medicine imaging to produce a three dimensional 3d picture of functional processes in the body. Wed like to help put your mind at ease a little and explain some of the differences between a pet scan and a ct scan. There is no radiation hazard risk for the patients undergoing an mri scan.

A major difference between a pet scan and a ct scan is the contrasting agents used in the body. If you have metal medical implants tattoos experience claustrophobia or may be pregnant you should notify your doctor prior to getting an mri pet or ct scan. If you need both an mri and a pet scan they can be done at the same time in a newer mripet machine.

While it sounds scary the tracer typically leaves your body a few hours after the scan. Petct scans provide significantly more information than ct scans and are far more reliable when diagnosing cancer. Mri vs pet scan.

While both are relatively low risk there are differences that may make each one a better option. The biggest difference is that mris magnetic resonance imaging use radio waves and ct computed tomography scans use x rays.
